WIRE FABRIC.

Specification of Letters-Patent.

Patented Apr. 26, 1921.

Application filed May 24, 1920. Serial No. 388,695.

To all whom it may concern:

Be it known that 1, WILLIAM it. BAKER, a citizen of the United States, residin at Waco, in the county of McLennan and S tate of Texas, have invented certain new and useful Improvements in Wire Fabrics, of which the following is a specification.

This invention relates to certain new and useful improvements in wire fabrics such as are used in making baskets, animal cages and traps, stock nozzles'and fences, etc.; and the primary object of the invention is to provide a fabric in which metal strips or ribs and cross rods are united without the use of extraneous fastenings and with a minimum of bending so as to not weaken the parts by excessive bending.

The invention further aims to provide a fabric which can be automatically produced by machinery and also economically produced with inexpensive equipment, and to provide a fabric in which holes or the like are entirely eliminated in the union of the parts.

The invention still further aims to simplify the joint connections between the strap-like ribs and the cross rods and to provide novel means for holding the rods against longitudinal movement.

Further and other objects will be later set forth and manifested in the course of the following description.

In the drawings Figure 1 is a vertical sectional view of a stock nozzle illustrating the present invention;

Fig. 2 is a detail view in side edge elevation showing the manner of connecting the parts;

Fig. 3 is a detail view in perspective of a section of the completed fabric; and

Fig. f is a section on line l4 of Fig. 3.

In proceeding in accordance with the present invention metal ribs 1 of strip, strap, or ribbon form are employed and are passed through or between crimping or corrugating rolls which form the same with uniform corrugations or undulations having convex parts 2 and corresponding concave parts 3. Wire rods 4 are placed in the concavities 3 on one side of the strips 1, and due to the parts 2 and 3 being alike on both sides of the strips, it will be apparent that either side of the strips can be used equally well. Fig. 2 to its left shows the rods as initially placed in the cavities 3, following which the straps 1 are subjected to the flattening out action of a roller. or pressure device which mashes or flattens the corrugations as depicted to the right of Fig. 2. Thus the rods 4 are frictionally gripped by the metal strips 1 which com pletely encircle the rods; and due to the nose 5 resulting from the double thickness formed by the doubling over of the parts 2, the wire rods are securely and effectively held against movement.

For the dual purpose of increasing the effectiveness of the joint formed according to the foregoing and for preventing slippage or movement of the rods transversely 'of the metal strips, the strips are crimped or given a concavo-convex formation as depicted at 6 in Fig. 4:, this simultaneously imparting a corresponding contour to the parts of the rods held in the sockets. Thus an increased frictional contact is provided between the parts and the strength of the joint is great y augmented.

From the foregoing it will be apparent that no slitting, or cutting of holes or openings in the metal strips, is required and that frictional contact alone is relied upon in order to connect the parts. Further the wire rods are bent but slightly as shown in Fig. 4 and the metal strips are bent to a minimum, the bending moreover involving a double thickness provided as to one-half of the socket formed for the reception of the wire.

Further the bowing or the concavo-convex formation of Fig. 4 results in greater strength being imparted to the metal strips, reinforcing the same in an obvious manner.

Owing to the width of the strips it will be apparent that they afford a relatively wide gripplng area for the wires, and in addition the bending of the strips does not appreciably weaken them.

What is claimed is:

1. In a wire fabric, transversely corrugated metal strips, and wire rods disposed in the concavities on one side of the strips, and the corrugations being flattened to completely encircle and tightly grip the rods, said strips and rods being formed with bowed parts extending transversely of the strips to hold the rods against movement transversely of the strips.

2. A wire abric composed of metal strips strips, said strips having bowed parts bep 10 tween the Wire rods, Which parts are flattened over to completely encircle and tightly grip the rods, and also to form a double layer of metal which overlies the rods, said strips and rods being formed with bowed parts extending transversely of the strips .1 to hold the rods against movement transversely of the strips. v

In testimony whereof I have signed my name to this specification.

WILLIAM E. BAKER.
